The erosion of titanium aluminide intermetallic alloys
The erosion behaviour of titanium aluminide intermetallic alloys has not been widely reported in the scientific literature and is part of the current international research effort aimed at exploiting these materials for turbine engine and automotive applications. In the present study titanium …

The machinability of a gamma titanium aluminide intermetallic
… reported details the machinability of the gamma titanium aluminide intermetallic (-TiAl) Ti-45Al-8Nb-0.2C currently under evaluation to be the material of choice for blades and stators in the intermediate compressor (IP) and low pressure (LP) turbine sections of an aeroengine due to the alloys …

Reaction Synthesis of Titanium Aluminide / Titanium Diboride in-Situ Composites
… the effects of changing the stoichiometry of the titanium aluminide matrix, and the effects of extrinsic reaction variables on the behavior of the reaction were studied and compared to theoretical predictions. It was shown that changing the stoichiometry of the titanium aluminide did have an …

High temperature flow behavior of titanium aluminide intermetallic matrix composites
Al₃Ti, Al₅CuTi₂, and Al₆₆Mn₁₁Ti₂₃, intermetallic matrices reinforced with 30, 40, and 50 volume % TiB, have been produced by XD<sub>™</sub> processing and densified into bulk form by powder metallurgy techniques. The compressive flow behavior of the Al₃Ti and Al₅CuTi₂, composites have been …

The effect of nitrogen, niobium and temperature of the high temperature oxidation of titanium aluminide alloys
This is especially attractive for reducing the engine weight and increasing the thrust/weight ratio. Increasing the operating temperature and thereby the engine efficiency has approached the maximum possible operating temperature for currently used materials. A model set of three intermetallics -- …

The thermal conductivity of intermetallics
The thermal conductivity of titanium aluminide and several ruthenium-aluminium alloys has been studied from room temperature up to 500°C. Ruthenium aluminide is a B2-type intermetallic which is unusual and of special interest because of its toughness, specific strength and stiffness, oxidation …

Microstructure and tensile performance evolution during Titanium - 6 Aluminium - 4 Vanadium (Ti-6Al-4V) temporary hydrogen treatment
… unarticulated relationship between hydrogen and titanium aluminide (Ti3Al) as a gap in literature that has been sustained by the pervasive use of the repeated nucleation framework. It hypothesises that grain refinement of Ti-6Al-4V by temporary hydrogen alloying can cause embrittling effects …

Plasticity of γ-TiAl alloys
Gamma titanium aluminide alloys are emerging as a lightweight replacement to nickel superalloys, with current application in turbine stages of aero-engines, as well as in high performance automobiles and potentially the nuclear industry. The lack of toughness of its two constitutive intermetallic …

Numerical modelling of the tilt casting processes of titanium alumindes
… and optimisation of the tilt casting process of Titanium Aluminides (TiAl). This study is carried out in parallel with the experimental research undertaken in IRC at the University of Birmingham. They propose to use tilt casting inside a vacuum chamber and attempt to combine this tilt casting …
